Although I do not run 9.2, I am pretty sure that wine is included in the software package. If not installed per default, simply open Yast -> Software -> Install and Remove Software, select 'Search' from the 'Filter' tab and search for wine.
Once installed, you should be able to run your sims installer with the command wine <name-of-the-installer> from command line. Or connect .exe files with wine in the file associations menu of the KDE control center (under KDE Components). Maybe this is done already by the wine-rpm, so have a try to click on the exe.
